Title: Method and circuit arrangement for transmitting different signals from signal transmitting devices to signal receiving devices
Inventor: THOMANEK ULRICH FRANZ DR
IPC: H04L12/00
Filed: 1981-02-09
Abstract: The invention relates to a method and circuit arrangement for transmitting different signals from signal transmitting devices to signal receiving devices via a signal transmission network with individual transmission paths provided for the different signals. It is based on the principle that the signal receiving devices are in each case connected via converting devices (Con) to the signal transmission network (VSt). To guarantee signal transmission which meets different transmission requirements, it is provided according to the invention that, corresponding to the presence in each case of one of several transmission requests which differ from one another, the signal in each case to be transmitted is transmitted either via at least one channel (e.g. NK2) alone which is different from the channel (e.g. NK1) which is designated per se for its transmission or via said channel (NK2) and also simultaneously via the channel (NK1) designated for its transmission. The main field of application of the present invention concerns the transmission of data signals. <IMAGE>

Title: Method and tool for producing a porous filter block
Inventor: CORNELSEN JUERGEN
IPC: B01D39/20
Filed: 1981-04-15
Abstract: In the method for producing a porous filter block, in one operation a plurality of wire cloth strips laid one above the other are compressed between a die (1) and a pressure plate (6) with a pressure of 10 to 40 kp/cm<2>, the pressure plate (6) moving downwards against the action of springs (9) until the upper boundary surface aligns with the upper boundary surface of a die-plate (7). Punching out the filter disc package from the wire cloth strips lying one above the other then follows. In this case, the die (1) is introduced into the recess of the die-plate released by the pressure plate (6). The pressure plate forms an elastic abutment during the punching operation. The downwards movement of the pressure plate (6) is limited by a baseplate (11), against which strikes the lower boundary surface of the pressure plate. The punched out filter disc package, in the course of a further pressure loading by the die (1), which is between 100 and 1200 kp/cm<2>, is cold-formed to give the desired porous filter block. <IMAGE>

Patent DE-3125640-A1 (DE)
Inventor: DOBLER KLAUS DR ING
IPC: G01L9/04
Filed: 1981-06-30
Abstract: The sensor, intended to detect de pressure of a medium, employs at least one element modifying its resistance value under the effect of a pressure. Said element is an ordinary resistive element, preferably a coal layered resistance, a thin layered resistance or a thick layered resistance. The elements (21) are preferably arranged in a bridge circuit wherein, in order to compensate for the temperature influences and to increase the pressure-dependent signal, resistive elements are used which have different temperature and pressure coefficients. The resistive elements are further arranged in a support (32) which may be resiliently deformed under the effect of the pressure, so as to obtain an increase of the signal by the conjugated effect of the pressure and an expansion, respectively of a deformation of the resistive element.

Title: Device for adjusting the axis of rotation of a joint for the swivellable suspension of a radius arm of a wheel on the body of a motor vehicle
Inventor: KOENIG WERNER ING GRAD
IPC: B62D17/00
Filed: 1981-08-06
Abstract: The device for adjusting the axis of rotation of a joint for wheel radius arms of motor vehicles has eccentric plates rotatably and fixably seated on the axis of rotation, which plates are guided in guides arranged perpendicular to one another. By rotating the eccentric plates it is possible to shift the axis of rotation, held in a bearing bracket arranged on the body of a vehicle, in radial directions perpendicular to one another, it being impossible for this adjustment to vary once adjustment has been performed in the one radial direction, when thereafter adjustment is undertaken in the other radial direction, and the adjusted eccentric plates being torsionally secured in the process. The invention thus offers the advantage that only the axis of rotation then has to be correspondingly adjusted, relative to the bearing bracket fixed on the vehicle body. The construction of the bearing bracket can thereby be of simple and compact design.

Title: Electrochemical battery
Inventor: BECK FRITZ PROF DR
IPC: H01M10/36
Filed: 1981-09-12
Abstract: The purpose of the present invention is the reversible storage of electrical energy in an electrochemical secondary cell. The battery operates at normal temperature. As the electrolyte it contains a solution of from 10 to 90 % by weight of hydrogen fluoride in water. The positive electrode consists of crystalline graphite, preferably in the form of a composite electrode made of 85-65% of flakes of natural graphite and 15-35% of polymeric binder, e.g. polypropylene. The material of the negative electrode is a metal from the group comprising copper, lead, iron, cadmium, zinc and manganese. The electrolyte forms intercalation compounds with the positive electrode and forms electrodes of the second type with the negative electrode. The electrodes can be employed in non-porous form. The following properties, beneficial for industrial application, have been newly found:   - Reversibility of the graphite fluoride electrode even in the presence of water. The reversibility in the anhydrous system is less than in 60-80% HF. - Considerably more positive open-circuit potentials than with other graphite salts (cf. Figure 1).   - Formation of reversible metal electrodes of the second type.   Secondary cells based on the present invention are highly cyclable and have an increased energy density. <IMAGE>

Title: Method and apparatus for monitoring the operating state of toothed gears
Inventor: WUESTNER HELMUT G ING GRAD
IPC: G07C3/00
Filed: 1981-09-15
Abstract: To monitor the toothed gears of heavy drives, such as, for example, the crown-gear drives of rotary tubular kilns, tube mills, driers, etc., in respect of the load-bearing pattern of the load flanks and lubricant supply, the temperature of the load flanks is recorded and monitored continuously by means of radiation-temperature measuring instruments. A measuring signal describing the temperature profile over the width of a gearwheel (1) can be obtained and can be used in any way alone or in conjunction with other parameters describing the operating state of the drive. This affords the possibility of being able to recognise at an early stage a non-uniform load distribution on the tooth flanks, caused by displacements of the shafts of the respective pair of gearwheels and adverse changes in the lubricant supply. <IMAGE>

Filed: 1982-01-23
Abstract: In a process for the purification of waste gas containing CO2 and other acidic constituents, in particular SO2, in which the waste gas is scrubbed in an NH3-containing scrubbing solution, from which pollutants such as H2S, HCN and the like present in the starting solution have been substantially removed prior to feeding it to the scrubber, the pollutant-containing starting solution is treated in a stripping column in counter-current with a part-stream of at most 12% by volume, preferably 3 to 5% by volume, of the waste gas to be purified and the stripped solution is fed to a scrubbing tower as the scrubbing solution for the main quantity of the waste gas to be purified, while the pollutant-containing gases produced in the stripping column are fed to an incineration plant. The gases withdrawn from the stripping column can either be oxidatively combusted and the gas resulting from this passed into the scrubbing column or be subjected to combustion in a Claus plant or a plant for the production of H2SO4 or can be fed to coke-oven gas. A part-stream of the used scrubbing solution is oxidised with air with addition of NH3 in an oxidiser, and a part-stream of the oxidised solution is reacted with addition of lime to give calcium sulphate.
